SPECIFICATION forming part of Letters Application filed May 9, 1883.

To (0Z1 whom it may concern.-

.Be itlznown that I, \VARD \Y. Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lamps, 01' which the following is a specification.

My invention relates to ear or other lamps which are suspended from the roof; and its object is to provide means for suspending the lamp which shall be simple, strong, and convenient for use, shall permit the free radia- 2 tion of light in all directions, and shall not interfere with the use of a reflector of any size or shape desired.

Hy invention consists in the parts and coinbina tions hereinafter described.

The special features of my invention will appear from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a vertical central section of a lamp embodying my invention, showing likewise a part of the car or other roof and the hood or jack surmounting the same. Fig. 2

is a plan of the part of the lamp below the Fig. i; is a view from below 1 line i 2, Fig. l. V of the part of the lamp above line 3 3, Fig.1.

Fig. 4 is a vertical sect ion of the lower part of the lamp, the oil-pot having been removed and the lmrner-plate l7 swung down.

A frame or spider, 5, Fig. l, spans the openingin the car-root l5, and a supportingrod, it, depends from the center thereof, which rod in the present instance is made tubular, partially to secure great stit'fn At the lower end of su jiporting-rod ti is secured a glol'ie-siipport, T, on which rests the globe 19. The upper end of the globe is steadied by the metal top 20, which extends up into the ring 21 of the spider 5. A reflector, 13, surrounds the metal top 20 immediately above the globe.

The oil-pot t has an upwardlyprojecting pin,

9, which may be inserted in the lower end of the tubular rod I3, said pin being shouldered at 10 and provided with a transverse hole, through which the catch ll may pass when the oil-pot is in its normal position. The spring-catch 11 is carried by the globesnpport 7 and is pressed inward by a spiral spring, 12. Theshoulder l0 enables the pin 11 to \Viniprrs, of 1 Patent No. 395,937, dated January 8, 1889.

sustain the oil-pot in the position shown in dotted lines, in which position the burners t are accessible for lighting. 1 The hood it needs no special description, as it forms no part of the present invention, t and its structure is clearly shown in the drawings.

Referring now to Figs. 2 and 3, it will be seen that burners it] are placed in opposite sides of the oil-pot and project through holes in the burner-plate 17. Air is supplied to the burners through perforations 22, a part being directed against the flame by the burner-caps and a part issuing through the perforations 25 in the b1l111l'1)l1t6 17 partially for the purpose of cooling said plate as well as for sustaining combustion. The burner-plate 17 is hinged at one side to the globe-support, the opposite side being sustained by the springcatch 18. Vhen the oil-pot is removed, the burner-plate l 7 may be swung down, as shown t in Fig. 4:, thereby leaving openings of sufficient size to admit the hand to the inside of the globe for cleaning the same.

It will be seen by reference to Fig. 1 that the parts of the lamp which would cast shadows are reduced to a minimum, and that light from one or the other of the burners is radiated freely in all directions except downward. The reflector may be made with surfaces of i such angles and dimensions as to entirely neutralize the shadow of the oil-pot within a short distance of its bottom. The absence of any outside supporting-arms, which, if used, must either surround the reflector or pass through it, enables me to use a reflector having an unbroken surface and of any dimensions and shape best suited to destroy the shadow of the oil-pot.

Lateral steadiness is given the lamp by securing the globe l9 and metal top 20 firmly between the globe-support 7 by means of the rod 6, acting as a tie-rod, and spider 5, so that I the stiffness of the tube 0 need not be solely depended upon for this quality.

y The supporting-rod (1 may in general be 1 solid or tubular. The lower part must be I tubular in this particular instance, because I the catch herein used for sustaining the oilhe ompli'ryod in oonnoctiou with my invont ion which would permit the use of :1 Solid rod and I thorotiorc contemplate snoh :1 rod us within the soopo of my invontion.

I claim- '1. In a lamp, :1 gloho-holding device consisting' ot a bottom gloho-snpport', in (=omhi nation with u spidor soourod to the roof or veiling and it rod depending therefrom, runj ning' through Said glohe, and connooting said, i
